It's subtle and I didn't even hear it until a friend pointed it out, but Josh Ritter's "Lantern" features two repeating guitar patterns left and right which continue throughout the song. One is 6/8, one is 7/8. The song itself is in 4/4.

How do you use them? Any favourite ones (I'm quite into 3 against 4 at the moment)?

Would be cool to hear some examples of brilliant use of polyrhythms, anyone care to analyze some tunes?

I been trying to do this too. I have a band and I want the guitarist to have a solo just having 16 notes grouped in 6 (sixtuplets) while the bass plays another rhythm just using regular 16 notes. Would sound interesting but melodically, kind of hard to pull off

I did a surf-rock version of CAROL OF THE BELLS which has a hemiola polyrhythm in it (in the third time round). The main rhythm is 3/4 but it's got 2/4 (4/8 really) rhythms running against it. My brain melted when I was tracking it.

So I have been thinking about this for the last few days. A really interesting subject and I have to admit that not something I was ever aware of before. Of course I am a Radiohead fan and thus have listened to Let Down this week, probably about a hundred times, to try and get a feel for this idea.

So what is the best approach for writing and recording something like this? Let us imagine you were in your home studio now and recording Let Down. Would you record the bulk of a song in 4/4, then record the guitar separate over a 5/4 drum track, and then pasting the track into the main song? I am keen to try something like this just to see how it goes.

Learning to tap both rhythms simultaneously with your hands is a good start.

the deadmau5 thing and the wynton thing are actually cross-rhythms though.

cross-rhythms = when you put in a phrase of a different time signature that takes up the same amount of time as the original phrase.

i.e. if you made a 3/4 phrase fit into 4/4 time (triplets)
or for a more complex fit - subdivide 7/4 into 16th notes and group them by 5 you would get a 4/4 over 7/4 cross-rhythm.

polyrhythms = when you have phrases of the two different time signatures happening at the same time but they don't take up the same amount of time.

i.e. if you had a 5/4 over 4/4 polyrhythm, the 5/4 phrase would end on the 1st beat of the next 4/4 bar phrase. If it were to repeat, the next 5/4 phrase would end on the 2nd beat of the following 4/4 bar phrase.

Well a cross-rhythm is a polyrhythm (at least according to all the definitions I've read). The examples of polyrhythm I've seen (few examples below) all take up the same time. Could you post an example of what you define as polyrhythms?

I believe there is a difference between polyrythmn (two different rythmns played together, but in the same time signature) and polymeter (two different time signatures being used by different instruments). Led Zep Kashmir is a polymeter. I think Status Quo 'Rockin all over the world' is a polyrythmn - mixing straight and shuffle time. This is what Sound on Sound said about it:

I can't recall The Beatles using a polyrythmn or polymeter as I understand it, but they certainly mixed up time signatures, which creates a similar unsettling effect. They would insert a 3/4 section into a 4/4 song, or just cut out a beat or insert one as needed. Thinking of "She said she said" and "We can work it out" as examples.

Check out "Good Morning Good Morning" for a most unusual rythmn ... here is what wikipedia says about it:

And yet the song flows and feels right.

I love unusual time, regardless of how it's created. I think it's a key ingredient for avoiding boredom in a song - along with unusual chord changes or modulation, and unusual lyrics. The elephant of surprise.

One of my favorites for this is Manfred Mann - 'Ha Ha Said the Clown' - that did my head in for days until I got it ... addictive.

As somebody mentioned above - Chuck Berry was a king of Polyrhythm ... a lot of those old r&b or r&r songs had a strange mix of straight and shuffle timing that always used to throw me ... part of the voodoo ...

Poly simply means "many". So you can put more than one rhythmn together, and both can be 4/4. Polyrhythmn should not be confused with Polymeter, such as Led Zeps Kashmir where the drums stay in 4/4 but guitars and orchestra play a 6/4 part that only coincides on the One every 12 bars ... fun stuff to play and compelling to listen to.

And simply cutting out or inserting the odd beat here and there to make songs cooler is something else and best done by feel. I'm sure Burt Bacharach and Lennon, McCartney & Harrison never really thought to much about what time signature they were in when they wrote. Burt would have had to think about it when he notated it, and George Martin would have figured something out for The Beatles.

Some of the timing effects were created with tape editing. For example in McCartneys's Let Me Roll It, there is a cool timing bit where a bar gets repeated and that was a tape edit mistake that sounded so cool they kept it.

If writing a song and it starts to get a bit boring, consider chopping a beat out to make it cooler. Or adding some beats as required. Force dancers to change their leading foot ...

I always find the timing of that song from Babe (the pig movie) ... to be very compelling (If I had words to make a day for you) ... and even 'How Great Thou Art' has an interesting timing that throws most people. Imo it's all part of why those songs were massive hits in their day. I actually think it's a feature of some older church music that influenced Western music.

Poly simply means "many". So you can put more than one rhythmn together, and both can be 4/4.

That's weird, I've never heard anybody use the term polyrhythm that way before and I'm not sure why that distinction would even be necessary. If you put two rhythms together and both are 4/4 that just seems like "rhythm". Wouldn't that include basically all rhythms ever? Like straight 8th note hi hats over kick on the 1 & 3 and snare on the 2 & 4 would be a "polyrhythm" under that definition wouldn't it?

I guess semantically it sort of makes sense but then musically I don't see any reason for the term polyrhythm if you define it that way. But in popular usage I don't think anyone ever means that when they say polyrhythm do they? If you look at the wiki entry on polyrhythm it's all about rhythms in different meters that are overlaid on top of each other.

After some more reading the best I can come up with is that apparently some people make the distinction that polyrhythm refers only to rhythms where two meters are overlaid but end on the same downbeat at the beginning of each bar? While polymeter would be combinations that take multiple bars to phase back onto the downbeat together? This thread sort of helped clarify but also seems equally confused and unresolved Meters, polymeters, polyrhythms, compound meters. What are the differences? - TalkBass Forums

I'm still not really sure why the distinction is useful in any practical sense.

To get back to the original subject, I know this is obvious (and maybe a tad trite to some members), but Sting is a master of Polyrhythmic-yet-SIMPLE pop writing. He has this incredible knack for writing in complex meters that don't sound particularly sophisticated or tricky until you try to play them. Some of them were pretty big hits in their time.
